U-turns

We currently tow a 31' (I just measured it) 5th wheel with an extended pin box. I can "almost" make a full lock 3.5 lane U-turn with it without tapping the back of the cab of our short bed F250 and the hitch in it's 3.5" forward of the axle position. With a previous 26ft 5th wheel, I could do a full lock three lane U-turn with our 2500HD ram short bed with the hitch 3" forward of the axle with plenty of clearance. We're thinking of going back to a travel trailer of about 30ft. Curious to what approximate length it typically becomes impossible to do a full lock U-turn without contact based on your experiences. Our ol' 19' Aljo TT would follow us anywhere with plenty of clearance going forward. I haven't towed a longer travel trailer. Not an exact science I know. Just trying to get a rough idea.

There are a LOT of variables. The WB of the TV. The length of the TT tongue. How severe of an angle can the TV wheels turn. Length of the drawbar. Where the TT wheels are located. Even the shape of the front of the TT. (To make it worse, all this changes when turning on a slope such as a steep driveway) And probably some more that escape me at the moment.

Unless someone hear has excactly what you are contemplating, it will all be a guess.
